Description

Local monitor R6 class

Details

See crew_monitor_local().

Methods

Public methods

• crew_class_monitor_local$dispatchers()

• crew_class_monitor_local$daemons()

• crew_class_monitor_local$workers()

• crew_class_monitor_local$terminate()

---

Method dispatchers()

List the process IDs of the running mirai dispatcher processes.

Usage

crew_class_monitor_local$dispatchers(user = ps::ps_username())

Arguments

user

Character of length 1, user ID to filter on. NULL to list processes of all users (not recommended).

Returns

Integer vector of process IDs of the running mirai dispatcher processes.

---

Method daemons()

List the process IDs of the locally running mirai daemon processes which are not crew workers. The crew_async() object can launch such processes: for example, when a positive integer is supplied to the processes argument of e.g. crew.aws.batch::crew_controller_aws_batch().

Usage

crew_class_monitor_local$daemons(user = ps::ps_username())

Arguments

user

Character of length 1, user ID to filter on. NULL to list processes of all users (not recommended).

Returns

Integer vector of process IDs of the locally running mirai daemon processes which are not crew workers.

---

Method workers()

List the process IDs of locally running crew workers launched by the local controller (crew_controller_local()).

Usage

crew_class_monitor_local$workers(user = ps::ps_username())

Arguments

user

Character of length 1, user ID to filter on. NULL to list processes of all users (not recommended).

Details

Only the workers running on your local computer are listed. Workers that are not listed include jobs on job schedulers like SLURM or jobs on cloud services like AWS Batch. To monitor those worker processes, please consult the monitor objects in the relevant third-party launcher plugins such as crew.cluster and crew.aws.batch.

Returns

Integer vector of process IDs of locally running crew workers launched by the local controller (crew_controller_local()).

---

Method terminate()

Terminate the given process IDs.

Usage

crew_class_monitor_local$terminate(pids)

Arguments

pids

Integer vector of process IDs of local processes to terminate.

Details

Termination happens with the operating system signal given by crew_terminate_signal().

Returns

NULL (invisibly).
